Cosori Air Fryer Stopped Working: 

There could be multiple reasons for any air fryer not working. For instance:

Electrical issue: Sometimes, the power supply to the cosori air fryer is insufficient. As a result, the air fryer model isn’t able to properly activate and start working. This electrical power issue could be due to the following reasons:

Following is the detailed guide to resolving the above issues:

CheckSolution
Inspect the power socket for functionalityReplace the faulty power socket
Check the breakerTurn the breaker ON
Check power cableReplace the power cord if it’s damaged
Check the fuse If it’s blown out, replace it with one having similar specifications
Consult the manual for accurate power, wattage and voltage.The power should meet the cosori air fryer’s average power requirements

Overheating Issue: Some cosori air fryers stop working due to overheating issues.  The air fryer models are programmed to automatically shut off or deactivate if the air fryer starts getting overheated. This could be due to overcrowding and overfilling of the air fryer basket. This results in poor air circulation and hence the air fryer starts getting overheated. Moreover, irregular clean-ups can result in accumulation of the food crumbs over the heating coil. They start decomposing and block the heating element. Hence, the heating coil starts to overheat. This triggers the auto-shut-off function.

Apart from the debris clogging the coil and overcrowding of the fryer, the two top reasons for overheating coil be

Cosori Air Fryer Troubleshooting: 

Although it’s common for air fryers and other electronic devices to face some issues, the problem mentioned below is only cosori air fryer specific. Let’s discuss them in detail

Power Issue: Many consumers have reported their cosori air fryer not turning on. Even if the air fryer turns on, it shuts off halfway. This could be due to an interrupted power supply. 

Solution: If your new cosori air fryer is facing this issue, then it means that it’s still under warranty, immediately send it to the manufacturer for fixing. 

If your cosori air fryer is old and has stopped working; then check the following things:

  • Check if the power cord is damaged. Look for loose wiring, wear, tear or melting of the outer covering. If the power cord is damaged, then replace it with a new one. Ensure that you purchase the cord with the same power specifications. 
  • Check For Damaged Thermal Fuse: The cosori air fryers come with an internal thermal fuse that regulates the electricity flow. It is highly sensitive to power spikes and protects the main power circuitry from power spike damage. 

Therefore during an electrical surge, the thermal fuse protects the main system by blowing out. This cuts off the electrical supply and shuts off the unit Look for a broken glass body and then replace it with a thermal fuse having a new one having similar specifications.

Cosori Air Fryer Smoking: Some users have reported that their cosori air fryer gives off white smoke during cooking. This scared off some users as they thought this could be due to some potential electrical issue resulting in a fire hazard. However, the main reason why air freyr starts emitting smoke is due to us of excessive oil. The oil build-up results in smoke production. 

Solution: Reduce the oil using the foods. Moreover, clean the air fryer after every use to reduce the oil build-up. This will reduce the smoke.

Uneven Cooking: Some cosori users have reported uneven food cooking and even burning while using the air fryer. This could be due to the overfilling and overcrowding of the fryer basket. There is no heat circulation and hence hot spots develop and food starts to get burned. 

Solution: Place the food pieces with some distance between them. Don’t overcrowd or overlap the ingredients. Moreover, cook in single layers.

Cosori Air Fryer Fan Not Working:

The cosori air freyr fan may stop working due 

Dirt accumulation: During the cooking cycle, the oils and grease may splatter and reach the inside of the air fryer where the heating coil and the air fryer fan are located. The grease and oil over time can build up and clog the fan blades from rotating. This can cause the fan to malfunction. 

To deal with this, you need to monthly clean up the fan blades and fan base with a toothbrush and damp water to prevent oil buildup. Moreover, avoid using oil and grease or too much season on the food to reduce sauce splatter.

faulty motor: Loose internal wiring on insufficient power can cause the air fryer fan motor to stop working. The fan is driven by an electric motor. It powers its blades to rotate and provide vene heta distribution inside the great chamber. If the motor gets faulty, then you need to replace it with a new one. 

Obstruction of fan blades: If the fan blades are obstructed by food particles, or they have been bent, this can cause the fan to stop operating. You need to clean the fan blades and replace them if they have been corroded or damaged.
